Specification of Letters Patent.

Patented Sept. 24, 1907.

To all whom it may concern:

Be it known that we, WALTER GLENN ToDD, WIL- LIAM DRAKE HARRELL, and GEORGE TODD, citizens of the United States, residing at Wabash, in the county of Wabash and State of Indiana, have invented certain new and useful Improvements in Culverts; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Our invention relates to culverts and has for its object to provide a device of this class which is particularly simple to construct, cheap and easy to manufacture, strong, durable and eflicient.

With this object in view our invention consists in the novel construction of the culvert, and particularly in the tie rods, all of which will be first fully described and afterwards specifically pointed out in the appended claims.

Referring to the accompanying drawings: Figure 1.

is an elevation partly in section showing culvert. Fig. 2 is a vertical longitudinal section taken on line 22 of Fig. 1. Fig. 3 is a similar view showing a modification.

Like numerals of reference indicate the same parts throughout the several figures in which:

1 indicates the culvert which as shown in Fig. 1 may be constructed of independent sections wherever the culvert is too wide to be made of one section. The culvert is made of a suitable cement and a series of truss rods, 2 are arranged as shown within the arch and the cement allowed to set. At the ends of the trussrods 2 and connecting the same together are two straps 3. In Fig. 3 the truss-rod 2 is shown bent at an angle.

In operation the side sections of the culvert are formed with a wall extending a short distance above the culvert and all of the sections are constructed and taken to the foundation Where they are to rest without further work, except to [ill in the soil or gravel to extend to the top of the culvert, and should the foundation become defective at any time, the section covering that part of the foundation may be removed and the foundation repaired without removing the entire culvert.

Having thus fully described our invention, we do not wish to be understood as limiting ourselves to the exact construction herein set forth as various slight changes may be made therein which would fall within the limit and scope of our invention, and we consider ourselves clearly entitled to all such changes and modifications.

What we claim as our invention and desire to secure by Letters Patent of the United States is:

A culvert constructed of two or more independent longitudinal integral sections constructed of cement, each of said sections extending the entire length of the arch, a series of truss rods within the arch of each of said sections, said truss rods being longitudinally disposed in each section, and a transverse strap in each section at the ends of said truss rods to connect the truss rods in each section together independently of the truss rods in each fellow section, each side section being provided with a wall extending above the arch, each wall being integral with each side section, the whole being arranged whereby one or more of said independent longitudinal integral sections may be removed without disturbing the remaining sections.

In testimony whereof, we affix our signatures, in presence of two witnesses.
